000013808 520__ $$2eng$$aA web-based methodology for the prediction of approximate IDA curves, which consists of two independent processes, was recently developed within ICE4RISK project (http://ice4risk.sloprojekt.info/). The result of the first process is a response database of the single-degree-of-freedom model, whereas the second process involves the prediction of approximate IDA curves from the response database by using n-dimensional linear interpolation. The methodology is implemented by a web application, which enables user-friendly prediction of the seismic response parameters with higher accuracy than that which is provided by the currently available simplified approaches prescribed in various standards and guidelines. In order to demonstrate the capabilities of the proposed methodology, the web application for prediction of the approximate 16th, 50th and 84th fractile response of a reinforced concrete structure was developed. For the case study the response database was computed for a set of thirty ground motion records and the discrete values of the six parameters as presented in Figure 1. The developed application enables quadrilateral idealization of the pushover curve, including strength degradation. Structural collapse capacity can therefore also be estimated, which is demonstrated for typical reinforced concrete structure. Very good agreement between the computed and the approximated IDA curves was observed.
